摘要：
An optical information recording medium according to the present invention includes a first information recording layer on which information is to be recorded by laser light; and a second information recording layer on which information is to be recorded by the laser light which has passed through the first information recording layer. The first information recording layer includes at least one of a reproduction-only area and a recording and reproduction area. The second information recording layer includes a test recording area. At least one of the reproduction-only area and the recording and reproduction area, and the test recording area is located such that one of the reproduction-only area and the recording and reproduction area includes an area of the first information recording layer through which the laser light for recording information in the test recording area passes.
